Advantages of Ultrasonic flowmeters: # Flow measurements in large pipes can be done. Followings are advantages: 1. Disadvantages of Ultrasonic flow meters:

( Log Out /  How to solve magnetic flow meter measure flow disallow. The main advantage of doppler flow meter is its non-intrusive design. The other potential problem of this technology is that it can have trouble operating at very low flow velocities. 1. Appliable for various kinds of liquid, even if the chemical liquid, oil etc, not influenced by the medium status. Disadvantages of Doppler Flow Meter The main disadvantage of the doppler flow meter is the fact that the liquid stream must have particulates, bubbles, or other types of solids in order to reflect the ultrasonic signal. The ultrasonic flow meters are made using the ultrasonic transducers which are clamped to the external surface of a pipe to generate the ultrasonic pulses through the pipe.

Multiple signal output, can saitisfy what client needs. Ultrasonic flow meters have many applications, from process flow to custody flow. The ultrasonic flow meters are sophisticated when compared to the mechanical flow meters, so it needs experts to repair and maintain the flow meters. 2. There are two types of the ultrasonic flow meters which include the time of the transit ultrasonic flow meter and Doppler ultrasonic flow meter and these can be used for the pipe flow measurement without taking the pipe apart and the rail mounted transducers can be clamped to the outside of the existing pipe.

Generally, an ultrasonic flow meter is the device that uses ultrasound to measure the velocity of a liquid flow that helps in determining the volume of liquid flow also. 1. The main advantage provided is ultrasonic measurements are non-invasive. This signal reflects off particulate, either solids or gas bubbles. Affordable price can satisfy clients from any country of the world. Change ), You are commenting using your Twitter account. # Flow of both gases and liquids can be measured. Non-intrusive technology, no need cut the pipe or stop the flow, can realize online installation any time.

Works well with dirty or corrosive fluids. Ultrasonic flow meters are widely used gradually, but some customers are still not very familiar with this type of flow meters.

Only can measure the fluid with temperature range -30℃ ~160℃.

Their design is highly sophisticated and they do not obstruct the liquid flow, so they can be used for sanitary, corrosive and abrasive liquids. This frequency shift is proportional to the liquid’s flow velocity & is known as the Doppler’s effect. These are the advantages of the ultrasonic flow meters and there are many disadvantages of the Ultrasonic flow meter which include: The main disadvantage of the ultrasonic flow meter is the cost. This means that the doppler flow meter is not a good choice for the water and very clean fluids.

Advantages of Ultrasonic flow meters: 1. Standard product easy for stock, has ENGLISH, ITALIAN, TURKISH for selection. Only can measure the fluid with temperature range -30. Followings are advantages: Non-intrusive technology, no need cut the pipe or stop the flow, can realize online installation any time. 7.
